From ddf6d0a00cbb4ad6d4fb4200cc911bb9389174c1 Mon Sep 17 00:00:00 2001 From: "hawkes@sgi.com" Date: Thu, 13 Oct 2005 12:01:18 -0700 Subject: [PATCH] [IA64] another place to use for_each_cpu_mask() in arch/ia64 In arch/ia64 change the explicit use of a for-loop using NR_CPUS into the general for_each_online_cpu() construct. This widens the scope of potential future optimizations of the general constructs, as well as takes advantage of the existing optimizations of first_cpu() and next_cpu(), which is advantageous when the true CPU count is much smaller than NR_CPUS.
